with alined. bearings c, and the latter of which .being much the heaviest and disposed at the top supports the main operating parts.

In the pedestal is journaled a horizontal shaft f, which carries at its inner end two bevel-gears g 71-, its outer end carrying a loosely arranged pulley 1', whereby, through a belt or the like, power is taken into the machine. On thc shaft is keyed a block j. On the shaft is also mounted aclutch mechanism of the friction type, It, (which it is notthought necessaity to describe. since it may be of any suitable form,) whereby the said block may be operativelv connected with the revolving pulley in such manner that rotation will be imparted to the shaft. To actu-t ate the clutch, a fork l, engaging an annular groove in the block is provided, said fork being carried by a sliding rod 'm, which is arranged in bracketsm. on. the pedestal. In the bracket 12. which is the nearer to the free end of the rod is pivoted a latch 0. which by engaging a notch p in the rod holds the rod against the tension of a retractile s )ring q, which tends to throw the fork, and consequently the block, toward the pulley, in which position, it may be said, the clutch releases the pulley;

1' is the starting-lever, its function being to 3 move the rod against the tension of the spring i until. the clutch effects the connection of the l pulley and shaft and the latch catches and 1 holds the rod, to which latter said lever is .pivotally connected.

.9 indicates a post formed with a flange t at its lowerend and having its upper portion 11- 5 reduced and secured in the arm at vertically by set-screws v. A revoluble disk '10 is supported by this flanged post, its hub portion :1: being journaled on said post between its flange and the arm (1. Fixed to this disk, as by screws 1 is a bevel-gear 2, which meshes with the bevel-gear 9. To the lower end of the post is secured, as by a bolt 1, a block 2, which serves both as the chuck portion of the mechanism which holds the can and head assembled while undergoing the uniting operation and as a uide for certain parts, as hereinafter described.

At diametrically opposite points in the disk w are arranged pairs of levers. Since the structures which comprise these two pairs of levers are exactly'alike, except in a certain particular hereinafter mentioned, reference will be made specifically to but one. i

3 is a lever fulcrumcd in the disk, it's f'ulcrum being afforded by a boss 4, formed integral with' it and which carries a nut 5 for maintaining the lever in )lace. of this lever carries a roller 6, adapted to run in the groove 7 in the under face of the block 2, said groove being the guiding portion, already referred to, of said block and being The free end l I made to conform to the outline of the can, I i

table is elevated so as to force the as shown in the drawings) so that when the disk revolves the roller 6 follows a path coinciding with the outline of the can. ver 3 and another lever S are pivoted together at approximately their middle points by a bolt 9. The free end of lever S is bifurcated horizontally for the reception of a re movable knurl or shaping-roller 10, (see Figs.

8, 9, and 10,) while its other end carries a vertical stud 11, which projects up through an arc-shaped slot 12 in the fulcrum portion of the lever 3 and acts as a bearing at its upper end for an ant-i frietion-roller 13. l

The mechanism above described is duplicated, being marked A and B in Fig. 3. The lever S in mechanism A carries a knurl or shaping-roller like that shown in Fig. 9. The parts of. the can being assembled as in- Fig. 11, this knurl sha as their edges primarily. as in Fig. 12-. The lever S of the mechanism B carries a knurl which while it finally "sets" the metal, as in Fig. 13. gives it some selected Such a knurl appears in Fig. 10. where its acting surface is adapted to leave the roll constituting th finished joint with its top portion projected somewhatoutwardly, as in said Fig- 13. Levers S are the ones which act as the tools for shaping the metal. Levers 3 serve simply as their supports. Levers 8 take their general direction shoulder 1- forming a part of. the disk '11. is

revolubly arranged an annulus 15, formed with peripheralcams 16 and 16 andv with a bevel-gear 17, which meshes with the gear 71. These cams coincide for a considerable portion thereof. In their coinciding portions these cams are initially more or less abruptly inclined, as at 17, then very slightly inclined for a considerable distance, as at 17*, until they finally reach their highest elevations, at 18. At'lt) the periphery of cam 16 drops to an intermediate elevation, while at 20 it drops to its lowest elevation. At 20 cam 16 drops to its lowest elevation, which eleva- Said letion corresponds with elevation 20 of cam 16.

Against the cam 16 bears the rollcr13 of lever S in mechanism A, while against cam 16 bears the roller 13 of lever S in mechanism B. 2 is a table for supporting the can, it being carried by a vertically movable shaft 33, which is arranged in the bearings c and guided by an arnrZl, which is adjustably secured on the shaft by a set-screw and which engages a feather 26 on the pedestal.

brake-band surrounds the disk and. is normally pulled against it by the same spring (1 which controls the rod. As a support for its r Fig.1) for the gearing or any othersuitable Part Before describing the operation of the ,machine it should be stated that in that'embodiment of the invention shown the gearing 2 g h 17 is pitched so that six revolutionsimparted to disk w are equivalent to five revolutions imparted to annulus 15.

The starting position is where the lever 8 in mechanism A, which efi'ects'the shaping of the lowest elevation 20 of the cam 16, while the roller 13 of the lever 8 in mechanism B having just leftthe highest elevation 18.

placed on the table 22 with its head applie as in Fig. 11 and being raised against the chuck in block 2 by the depression of treadle 27 it will pass up in between the knurls freely. Lever r is then pulled upon until it has loosened the brake-band 31 on the disk w and moved the rod m far enough so that the latch catches and retains it. The consequent rotation of shaft f results in the rotation of the disk and the annulus 15, the former at a laster rate than the latter, as already explained. The disk thus gains on the cam, whereby the roller 13 of the lever 8 of mechanism A, which does the primary bending of the metal, is caused to ride up on cam 16, forcing the knurl of said lever against the work. In the position just referred to the lever 8 of said mechanism A is maintained while the disk around the can. At the fourth revolution of disk w the aforementioi'ied roller 13 runs knurl of the lever which carries said roller is permitted to withdraw from the work under actuation of its spring 21. By this time the roller 13 of the lever 8 of mechanism B has run up on cam 16, bringing the knurl of this By the time this and the next two revolutions of the disk have been cmnpleted said roller 13 will have run .down onto the portion 20 of the cam 16, while the other roller ]3,will have run down onto the portion 20 of cam 16. Thus both knurls will be again perfectly clear of the work. Upon this the stud 11 of roller 13 of mechanism B is brought into the path of the latch 0, tripping the same, and thus permitting rod m to retract, so that the clutch is rendered idle and the brake-band 31 pulled against the disk, so as to at once stop the it is capable of uniting thehead,
